CMatrix:Rows
The Rows method returns the maximum row index in the CMatrix. This is the number of rows needed to hold every possible index in a completely filled rectangular matrix.
number = CMatrix:Rows() |
On success, this method returns the maximum row index.
On failure, this method returns 0.
This method returns the maximum row index in the matrix. Since all indices do not have to be filled in a sparse matrix, the returned value is not the same as the number of rows. For example, if the CMatrix has 1 row with 2 members, one at index [1][1] and the other at index[1][10000], then Rows = 1.
Suppose a CMatrix assigned to M contains 3 members as shown below:
|
-- create a CMatrix |
|
-- set member 2, 44 |
|
-- set member 50, 20 |
|
-- set member 120, 2 |
|
-- result: Rows = 120 |
|
-- if finished with M, clean up memory |
